JSON

A flaw was found in the QEMU virtual crypto device while handling data
encryption/decryption requests in virtio_crypto_handle_sym_req. There is no
check for the value of src_len and dst_len in
virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow
when the two values differ.
